my guess is that you have download parameters deactivated this is usealy a setting ment to be configured by the user but some malware may affect that and cause you such problems. you can try
WMIC /OUTPUT:C:\ProcessList.txt PROCESS get Caption,Commandline,Processid
WMIC /OUTPUT:C:\ProcessList.txt path win32_process get Caption,Processid,Commandline
to view your parameters but i dont know much about that so i hope i helped
P.S. you can also back up and do a system resset
